Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber sensing systems struggle to effectively monitor a predetermined event when its location is unknown or changes, as they rely on pre-identified targets and lack the capability to dynamically adjust the monitoring target or location.
Innovation Solution
An optical fiber sensing system that includes an optical fiber for detecting vibrations, a detection unit to identify predetermined events based on superimposed vibrations, an identification unit to determine the occurrence location and movement destination area for an unmanned aerial vehicle, and a control unit to direct the vehicle to the appropriate location for monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical fiber sensing is used to detect vibration and identify predetermined events, then measurement precision is improved, but the system cannot properly monitor when event locations are unknown or change dynamically
Solution Approach 1:
The system dynamically adjusts the monitoring target and movement destination area based on real-time event occurrence locations. The control unit updates the movement destination area whenever a new event is detected, allowing the system to adapt to changing event locations rather than relying on pre-defined static monitoring targets.
Solution Approach 2:
The system uses feedback from the optical fiber sensing data to continuously update the monitoring strategy. The detection unit provides real-time information about event occurrences, which the control unit uses to adjust the movement destination area and guide the unmanned aerial vehicle to new monitoring locations.
2Device complexity
If unmanned aerial vehicles are allocated to pre-identified monitoring targets, then device complexity is reduced, but monitoring effectiveness decreases when events occur at unknown locations
Solution Approach 1:
The movement destination area is defined as a dynamic zone that can be updated in real-time based on event locations. This dynamic definition allows the system to maintain simple device configuration while achieving reliable monitoring of unknown or changing event locations through continuous area updates.
